8 o'clock?

The rabbits clock is moving 13 hours per every 1 hour. At 12.00 the rabbits clock shows 12.00. And after 1 real hour, the rabbits fast clock shows 1.00 so it must have gone 13 hours.

At 1.30, the rabbits clock has gone half of 13 hours (6.5 hours).

1.30+6.5 hours= 8.00

I did have to think about this for a while but you have to remember that although the clock moves 13 hours every 1 hour it only gains 12 hours (1 hour of normal movement + 12 hours gain). So at a real time of 1:30 it will have gained 6 hours.

Yes, I think you're right

KenR and KaB£H1s3,

Thank you very much both of you for the very quick response and detailed explanation and discussion.

I think I finally understand the information provided in the question, which is the clock show the correct time on 12:00, 1:00, 2:00 etc... But it does NOT imply the complete hour showing by the clock is always the correc time. (which makes the clock useless unless there is another correct watch/clock is there for comparison). This is the point I got confused. It also relies on one important assumption - the clock run faster but in a way that is linear/proportional. Therefore, for each real hour, the hour hand of the clock moves forward 13/12 rounds, i.e. 13 hours clock's time. For 30 real mins, it is 6.5 hour clock's time, so 1:30 real time is showing as 7:30 (1:00 + 6:30) in the clock.

I have to say the question is not clear at all, maybe intensionally so...

Hopefully in real 11+ test, no such question will be present...
